I was not sure where to post this, but because it shows the resultant power or force of aerodynamics it's going in here.

Looking for ideas and/or pictures of drilled out parts - Page 16 - Pelican Parts Technical BBS

Not saying it would but I haven't studied the geometry in detail, so it's something I'd probably look at.

I have somewhere photos of a 911 on the race track with it's aftermarket fiberglass hood being sucked upward. Quite interesting what happens at speed.
